APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday December 7, 2008 (MJD 54808) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Dmitry Bizyaev Nathan De Lee (MARVELS) Jiang Peng (MARVELS) ---=== OBSERVING PLAN ===--- MARVELS until 09:18 (8.4 h), then BOSS/SEGUE (3.1 h) ---=== OBSERVING SUMMARY ===--- Marvels cartridges exposed: 3076 (c. 8) f. A, 3077 (c. 1) f. A., and 3078 (c. 5), f. A, but probably with a very low S/N for the latter. SEGUE plate 3154 (c 9) was exposed but didn't get enough signal. ---=== OBSERVING LOG ===--- Afternoon ---------- ntp_check ok iccSoundOff ok imager bias ok spectro bias ok Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00057164.fit -6.1 -3.9 -2.8 1.8 7.1 8.2 10.4 sdR-b2-00057164.fit -7.7 -6.1 -4.9 1.1 7.4 8.6 11.1 sdR-r1-00057164.fit -7.1 -5.1 -3.9 1.6 6.9 8.1 10.3 sdR-r2-00057164.fit -7.6 -6.2 -4.4 0.8 6.4 8.2 10.3 Spectrographs should be in-focus for +5 C. 23:30Z ventilation started. Sky is overcasted, with a small number of patches. Night: ----- 00:15Z enclosure off MS underfloor calibration 00:44Z gotoField with cart. 8 plate 3076 (MS survey) fk5 used 50 min MS exposure MS underfloor -- cart. 1 plate 3077 (MS survey) is mounted. Even fk5 cannot be found because of very dense clouds finally, fk5 found in a patch with large offsets. MS 30 min exposure MS underfloor calib. -- 03:17Z we closed the dome because efficiency of integration is 3-5%. On the other hand, clouds are getting thicker and suspicious radar returns are seen around the site. 05:39Z opened for a patch of clear sky. MS underfloor calib. cart 5 plate 3078 is mounted (MS survey). This exposure was affected very much by dense clouds. MS 50 min exposure phase micro (UNACKNOWLEDGED: 2008-12-08 06:24:49Z) - This is due to Connie works with the imager. Archiver errors are because of the same reason. Again the same cartridge one more time. Efficiency is very low. Very cloudy 09:55Z cart 9 is mounted. No stars are seen. fk5 used After dense clouds we got a patch, with 35% efficiency. 11:01Z precal 11:07Z science 1800 r2 is a little bit under 2.0, because of clouds 11:40Z science 1800 again not enough postcal -- 12:25Z dome closed 12:34Z endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7850 22:56Z 23:22Z 100 O 130.14 136.82 51 bias ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 57163, plate -9999 ------- 22:51 57163 0.0 bias 23:17 57164 0.0 bias ----- sequence 57164, plate 3154 ------- 23:21 57165 10.0 flat 23:23 57166 2.0 arc 23:26 57167 3.0 arc 23:29 57168 3.0 arc 11:03 57169 10.0 flat 11:06 57170 2.0 arc 11:39 57171 1801.0 target 12:12 57172 1800.0 target 12:15 57173 10.0 flat 12:17 57174 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:06Z 8 3076 203.49 -0.0214 83.58 -0.0046 25.37 0.0242 1.000000 02:34Z 1 3077 171.83 -0.0013 53.09 -0.0047 -19.30 0.0092 1.000030 11:01Z 9 3154 24.24 0.0024 56.93 -0.0017 200.22 0.0314 1.000190 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:06Z 8 3076 1.00000 1 1316 200 203 83.6 4.2 5 280 -- 1.5" 02:35Z 1 3077 1.00003 -295 1051 125 172 53.1 4.7 7 269 -- 2.0" 11:01Z 9 3154 1.00019 -1875 -293 100 24 56.9 2.7 21 269 -- 2.0" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:42Z 47 15 15 297 (WNW) 136 - 22:14Z 45 15 8 275 (W) 176 - 22:46Z 42 15 8 304 (NW) 210 - a lot of clouds 23:30Z 41 14 4 266 (W) 145 - '' 00:00Z 40 16 14 313 (NW) 94 - '' 00:31Z 40 12 8 299 (WNW) 107 - clouds 01:01Z 39 14 9 273 (W) 111 - '' 01:33Z 42 12 11 266 (W) 76 - '' 02:03Z 41 12 11 286 (WNW) 180 - dense clouds 02:35Z 40 12 7 269 (W) 260 - '' 03:05Z 44 8 21 289 (WNW) 184 - '' 03:36Z 44 11 25 298 (WNW) 165 - ' 04:08Z 43 11 16 303 (WNW) 142 - '' 04:40Z 42 18 20 291 (WNW) 195 - '' 05:12Z 41 19 14 263 (W) 202 - '' 05:45Z 41 17 19 268 (W) 192 - '' 06:17Z 40 9 18 272 (W) 251 - sparse clouds 06:47Z 39 8 8 263 (W) 232 - '' 07:18Z 38 7 21 282 (WNW) 235 - '' 07:51Z 39 9 23 271 (W) 228 - dense clouds 08:23Z 38 11 23 273 (W) 209 - '' 08:55Z 39 16 24 264 (W) 246 - '' 09:27Z 39 11 21 261 (W) 234 - '' 09:59Z 39 14 24 269 (W) 191 - '' 10:31Z 37 14 20 265 (W) 169 - '' 11:01Z 36 14 21 268 (W) 243 - clouds 11:31Z 37 13 19 270 (W) 256 - '' 12:04Z 37 13 17 264 (W) 278 - '' 12:36Z 36 16 21 262 (W) 293 - '' ---=== TELESCOPE STATUS ===--- 23:30Z - Began ventilation.
